how to create kaffinity mask

Hello,
i need select cpu cores on which will be processed dpc and isr.
And i have no idea how to create kaffinity mask, it is 64bit value, which is in registry as binary value.
I have 8 cores, 4 physical and 4 threads.
I don't even know which are physical and which threads and how to obtain such information.
I want to exclude 2 physical cores from processing dpc and isr.
Interrupt Affinity | Microsoft Docs
IoConnectInterrupt routine (Windows Drivers)
There is calculator, but i don't know if affinity mask is same as kaffinity mask and i didn't find anything usefull searching for kaffinity mask.

I found tool, which allow me to change it.
Interrupt Affinity Policy Tool and unexpected affinity mask type

But i have problem, i set affinity for usb devices, which are using driver usbport.sys and system assigned other drivers to cores i want to make dpc free.
I just need to set affinity for devices in registry which using drivers, that are displaying in latencymon.
I am currently looking for devices which uses tcpip.sys i looked to device manager and checked show hidden devices and open every network adapter -> drivers tab and there was nowhere tcpip.sys driver under these adapters which confuses me, because i woudl expect tcpip.sys would have to do something with network adapters. And yet looking for ntoskrnl.exe and ndis.sys, dxgkrnl.sys.
If know which devices correspond to this.
